GuanacoThe guanaco is a camelid found in the mountainous regions of Peru, Bolivia, Ecuador, Colombia, Chile, and Argentina. Guanacos are often found at high altitudes, up to 13,000 feet above sea level, except in Patagonia, where the southerly latitude means ice covers the vegetation at these altitudes. To survive the low oxygen levels found at these high altitudes the blood is rich in red blood cells. A teaspoon of guanaco blood contains about 68 billion red blood cells, about four times that of human blood. Photo credit -- source link
